Solution 1

To calculate the time, we need to use the formula for power, which is:

Power = Work done / Time

We can rearrange this formula to solve for time:

Time = Work done / Power

Given that Power = 3 kW = 3000 W and Work done = 825 kJ = 825000 J, we can substitute these values into the formula:

Time = 825000 J / 3000 W = 275 seconds.

Solution 2

To calculate the time, we need to use the formula for power, which is:

Power = Work done / Time

We can rearrange this formula to solve for time:

Time = Work done / Power

Given that Power = 3 kW = 3000 W and Work done = 825 kJ = 825000 J, we can substitute these values into the formula:

Time = 825000 J / 3000 W = 275 seconds.
